Simple Ham Radio Antennas

Here are some general comments from Ray: I have a small garden but my favourite amateur band is 160 metres. Problem? Yes, but there is a way round the problem. The aerial I describe in the video isn't the best, but it will get you on top band with, in my case, surprising results. And it's great on 80 metres through to 10. ----- Thanks for joining us today.

Here's another simple antenna project from Dave Tadlock (KG0ZZ).  This time, Dave makes some modifications in his original 2 meter quad antenna.  The current model is now fully portable and is suitable for a variety of portable and emergency situations.  Also, this quad antenna can be used in deed-restricted housing, since it sets up and takes down in only a few minutes. ----- Thanks for joining us today.

Many radio amateurs are exploring the world of the 630 meter band (472kHz-479kHz).  The main issue with this MF (medium frequency) band is the large antennas used to make contacts. In this video, Australian ham Peter Parker (VK3YE) shows us how to use simple equipment to get on this fairly new amateur radio band. Here are some of Peter's comments: 630m has great propagation but what about the antenna? Most of us lack the land for a full sized one. But you can still get some interesting results by loading up what you've got. In this video I try 200mW WSPR on 476 kHz. How far do I get? Watch and find out! PS: Like these videos?

Antenna Length Chart For those of us who build our own antennas, here's a handy, concise guide to making an antenna perfectly measured for your band of choice.  Of course, local environmental and ground factors will modify your antenna design. Here's the link if you wish to pursue the matter further:  https://www.qsl.net/w/w7lk/site/antennachart.htm Here's the full chart for your reference: Antenna Length Chart in Feet and Meters Antenna Length Chart in Feet and Meters   Ham Band Frequency (Mhz) 1/4 λ (Feet) 1/2 λ Dipole (Feet ) 1 λ Loop (Feet)   1/4 λ (Meters) 1/2 λ Dipole (Meters) 1 λ Loop (Meters)   160 1.800 130' 0'' 260' 0'' 558' 4''   39.6 79.3 170.2 1.850 126' 6'' 253' 0'' 543' 3'' 38.6 77.1 165.6 1.900 123' 2'' 246' 4'' 528' 11'' 37.5 75.1 161.2 2.000 117' 0'' 234' 0'' 502' 6'' 35.7 71.3 153.2   80 3.500 66' 10''

Thanks to John Sunders (VK4BZ) for this informative and well-produced video about portable antennas for SOTA (Summits On The Air) and other field operations. Among the antennas considered by John are the random length, multi-band dipole, and end-fed antenna configurations. Some of these antenna may work well in deed-restricted (HOA/CC&R) situations. ----- Thanks for joining us today. Aloha es 73 de Russ (KH6JRM).

If you want to boost the performance of your 2 meter rig, be it a HT or full-featured transceiver, then try this Co-linear design from "Sparky Projects." Here are the main points: Whether going for a walk, or backpacking, you may be interested in a portable antenna solution, this is a full size 3/4 wavelength co-linear antenna, with 75 ft (22 m) of cable for 2 metre amateur radio use, but contained in a 18" x 2.5" (460mm x 70mm) tube. The original co-linear was designed to be mounted on a car by Fred Judd (G2BCX), all I did was make it portable, telescopic, and added a ground plane system More details can be found here, along with photos and the original plan http://sparky-projects.co.uk/colinear... ----- Thanks for joining us today.

Thanks to Steve (KM4SLW) and his friends at "Ham Radio Portable" for this efficient, lightweight, inexpensive vertical antenna for the 20 meter and 40 meter Amateur Radio bands.   Although the antenna is designed for portable or field use, it can be used at your home station as well. Here are some details from Steve: he idea for this antenna came from the qrpguys.com website. This one is built to handle 100W on ssb. The box has one T157-2 powered iron toroid with 24 turns of 18ga. enameled wire. For 20m the core is bypassed as the antenna wire is already a 1/4 wave on 20m- 16'-5". For 40m , the connection uses the core that provides the inductance to make the wire electrically appear to be a 1/4 wave on 40 meters. The core has around
